Today I started a couple of preparations for the upcoming car season.
Last year the stock radiator turned out inefficient with the tuned UT engine, so I decided to go for an aluminum radiator and dual fans instead. Surprisingly this approach also saves a lot of weight. Stock radiator is 10.3kg and the alu is just 5.6 kg including fan(s)
. The new radiator didn't fit 100% as it turned out that it is 10mm taller than stock, so I need to lower it a little bit. I also need to weld on tabs for fastening the IC heat exchanger and included tabs didn't fit the aftermarket fans.

I also prepared the roof for carbon fiber so I shaved off a millimeter from it. I will use the roof as a plug and remove most of existing material from it once the CF skin has been casted. I have big expectations for weight savings when ready as I lost a kilo just by shaving it.
I have still not decided about the wing but made plugs for carbon fiber stands as well. Carbon fiber and resin etc has been ordered but delivery is delayed due to Covid. I am looking forward to start working with it, hopefully next week. Carbon fiber fabrication is new to me.

It is also time for MOT and I need to temporarily remove 140-150hp to pass inspection. I found a very "soft* wastegate that probably will remove the issue. Most likely a temporary "MOT ECU mapping* is needed as well.
